Abstract

DISPOSICIONES DE ENLACE TELEFONICO CUYOS APARATOS INDIVIDUALES SON GOBERNADOS POR UNA DISPOSICION CENTRAL CONMUTADORA MEDIANTE INSTRUCCIONES DE CONEXION TRANSMITIDAS EN FORMA INDIVIDUAL. DESPUESDE CADA SELECCION Y CONEXION DEL CORRESPONDIENTE APARATO A LA CENTRAL CONMUTADORA SE INTERCAMBIA ENTRE AMBOS INFORMACIONES PARA VERIFICAR LA CORRECTA EMISION DE LA INSTRUCCION Y LA SUBSIGUIENTE CONEXION DEL APARATO CORRECTO; Y POR MEDIO DE SENALES RETRANSMITIDAS DE ACUSE DE RECIBO SE VERIFICAN INDIVIDUALMENTE LAS DIFERENTES INSTRUCCIONES TRANSMITIDAS. DESPUES DE SU CONEXION SE TRANSMITEDESDE LA CENTRAL AL CORRESPONDIENTE APARATO UNA INSTRUCCION DE INICIACION, Y ANTES DE O PARA LA DESCONEXION SE TRANSMITE UNA INSTRUCCION DE DETENCION. LA DISPOSICION CENTRAL CONMUTADORA COMPRENDEUN DISPOSITIVO TRANSMISOR DE INSTRUCCIONES DE CONEXION Y DE DETENCION, Y UN DISPOSITIVO DISCRIMINADOR (CAPAZ DE RECIBIR Y EVALUAR LAS SENALES DE ACUSE DE RECIBO). CADA APARATO INDIVIDUAL CONTIENE UN MEDIO DE ACUSE DEÑ RECIBO (QUE RESPONDE A LA INSTRUCCION DE DETENCION).TELEPHONE LINK PROVISIONS WHOSE INDIVIDUAL DEVICES ARE GOVERNED BY A CENTRAL SWITCHING PROVISION THROUGH INDIVIDUAL CONNECTION INSTRUCTIONS. AFTER EACH SELECTION AND CONNECTION OF THE CORRESPONDING DEVICE TO THE SWITCHING CENTER, BOTH INFORMATION IS EXCHANGED BETWEEN VERIFYING THE CORRECT ISSUANCE OF THE INSTRUCTION AND THE SUBSEQUENT CONNECTION OF THE CORRECT DEVICE; AND THROUGH THE RECEIVED ACKNOWLEDGMENT SIGNALS THE DIFFERENT INSTRUCTIONS TRANSMITTED ARE INDIVIDUALLY VERIFIED. AFTER ITS CONNECTION, AN INITIATION INSTRUCTION IS TRANSMITTED FROM THE CONTROL UNIT TO THE CORRESPONDING APPARATUS, AND A DETENTION INSTRUCTION IS TRANSMITTED BEFORE OR FOR DISCONNECTION. THE CENTRAL SWITCHING PROVISION INCLUDES A TRANSMITTING DEVICE FOR CONNECTION AND DETENTION INSTRUCTIONS, AND A DISCRIMINATING DEVICE (CAPABLE OF RECEIVING AND EVALUATING RECEIPT SIGNALS). EACH INDIVIDUAL DEVICE CONTAINS AN ACKNOWLEDGMENT RECEIPT (RESPONDING TO THE DETENTION INSTRUCTION).
